A simple way to deal with the distortion of the WCDMA power amplifiers has been proposed. The predistortion linearizer allows adjustment of the AM-AM and AM-PM curves to compensate the power amplifier nonlinearities.

• 针对宽带码分多址(WCDMA)功放的非线性失真问题,提出了一种简单有效的解决方案,即通过预失真发生器对幅度-幅度(AM-AM)及幅度-相位(AM-PM)曲线进行调整,以补偿功放的非线性失真。
